Since meeting for the first time on 13 October 1894, the clubs have played 204 times. The Gunners have 77 wins to United’s 82.

Apart from last season’s final, Manchester United have never met an English club in the UEFA Champions League.

Arsenal have faced English opposition in Europe on two previous occasions, losing quarter-finals to Chelsea in 2003/04 and Liverpool last season.

United’s ten preceding semi-final appearances have brought just three victories, the most recent being last season when they eliminated Barcelona on their way to a final victory against Chelsea in Moscow.

Arsenal have a 100 per cent record in UEFA Champions League semi-finals, having beaten Villarreal in their only previous appearance in 2005/06.

The clubs are the only teams to win the English league and FA Cup double three times. United did it in 1994, 1996 and 1999; Arsenal in 1971, 1998 and 2002.
